Yes I did.

And what was the result, I mean did it open the correct mxcl or did it open any other version or copy. I think the problem here is that you have more than one version of Maxwell installed in your system (or several copies and only one with the license) and the plug-in is finding the incorrect one. The way to check it is double-click in a mxs file and check where the mxcl that launches is located (right-click in the icon of the dock and select 'show in finder' ). If it's not the correct place delete that copy (emptying trash) and check again.

Best regards,
